Othewise, you can continue to shoot with it, and put up with degraded images. An estimate for repair might tell you if it's worth it, or you should be shopping for another lens. I would assume a dissasemble and clean might cost more than another used lens. And if paint inside is flaking, it might take more than a simple clean up inside. luck
